Fig. 1 is a diagram illustrating a cutting process of a conventional and undisclosed cut substrate 130, wherein a fixing structure (not shown) for fixing a large substrate 130 to be cut is correspondingly disposed on a first cutting machine 110, and when the large substrate to be cut is transported to the cutting machine 100 and correspondingly placed on the first cutting machine 110 and a second cutting machine 120, a cutting device 150 is pressed down to cut the large substrate 130, so as to obtain a finished substrate 130 on the second cutting machine 120, where the finished substrate 130 includes two layers of glass substrates, and after the cutting is completed, an upper layer of the glass substrate of the finished substrate on the second cutting machine 120 generally protrudes relative to a lower layer of the glass substrate.
The inventors have found that if the second cutting machine 120 is directly moved horizontally to be taken away from the first cutting machine 110 and transported to a designated position by the grabbing device 160, the finished substrate 130 may be partially adhered to the main body of the large substrate due to insufficient penetration during cutting, and the problems of incomplete breaking, even breakdown, and abnormal quality of the finished substrate may occur. Specifically, if the first cutting machine 110 and the second cutting machine 120 perform cutting in a flat state, the large substrate is cut in the flat state, the knife pressure range is small, and the fault tolerance rate is low. In addition, the lower side surface of the upper glass substrate is generally provided with metal wiring structures, and the metal wiring structures are horizontally separated from each other, which may cause the metal wiring structures near one end of the first cutting machine 110 to be subjected to an acting force, thereby causing problems such as wire breakage and scratching.
The inventor improves the method, and the improvement scheme is as follows:
the present application is described in detail below with reference to the figures and alternative embodiments.
Fig. 2 is a flowchart of a method of a cutting method for cutting a substrate according to an embodiment of the present application, and discloses a cutting method for cutting a substrate, including the steps of:
s1: placing a large substrate to be cut on a first cutting machine table and a second cutting machine table of a cutting machine table;
s2: adjusting the cutting device to the cutting position of the substrate to be cut, and cutting the large substrate to be cut to obtain a finished substrate falling on a second cutting machine platform;
s3: after cutting, driving a second cutting machine table according to preset parameters to enable the second cutting machine table and the first cutting machine table to form a leading-off height difference;
s4: driving a second cutting machine to lead away from the first cutting machine so as to lead away the finished substrate obtained by cutting from the large substrate;
s5: and conveying the finished base plate obtained by cutting to a specified position, and resetting the second cutting machine to an initial state.
After the cutting is finished, the second cutting machine 120 is directly moved horizontally to be led away from the first cutting machine 110 and conveyed to the designated position through the gripping device; after the cutting is completed, according to preset parameter adjustment, the second cutting machine table 120 is driven to lift, so that the first cutting machine table 110 and the second cutting machine table 120 form a leading-away height difference, particularly, the leading-away height difference enables a large substrate on the first cutting machine table 110 to form a height difference with a finished substrate 130 separated from the large substrate 130 and falling on the second cutting machine table 120, and the height difference is formed between the finished substrate 130 and the finished substrate 130, so that the splitting action is performed, the splitting at the cutting position is more thorough, the problems of abnormal quality and the like caused by insufficient penetration and direct leading-away of the cutting device 150 are solved, and the quality of the finished substrate 130 is improved.
Specifically, the preset parameter is a parameter for lifting the height of the second cutting machine, the preset parameter can be adjusted according to different properties and models of the cutting substrate, and the leading-away height difference is formed in other ways: the one end of second cutting board is lifted, certainly also can be with the whole lifting of second cutting board, specifically as follows:
fig. 3 is a flowchart of a method of a cutting method for cutting a substrate, and referring to fig. 3 in conjunction with fig. 2, in particular, the step S3 includes a process of:
and S31, after the cutting is finished, lifting one end of the second cutting machine close to the first cutting machine according to the angle parameter, so that the second cutting machine and the first cutting machine form a leading-off inclined angle.
The preset parameters include angle parameters, the setting of the angle parameters is equivalent to the setting of a leading-off inclination angle, specifically, one end of the second cutting machine table 120 close to the first cutting machine table 110 is lifted, so that the problem of insufficient cutting penetration is thoroughly improved due to the existence of the leading-off inclination angle by splitting the glass substrate between the finished product substrate 130 and the large substrate 130, and the metal wires on the surfaces of the two substrates can be separated in advance, so that when the second cutting machine table 120 is led off from the first cutting machine table 110, the problems of scraping damage and the like caused by the direct horizontal leading-off of the metal wires can be solved.
Of course, the lead-away height difference is formed by other methods, and the step of S3 includes:
after the cutting is finished, the two ends of the second cutting machine table are lifted integrally according to the preset angle parameter to form a leading-away height difference.
The second cutting machine 120 is integrally lifted, and the height difference is integrally led away, so that the finished substrate 130 is cracked more thoroughly, and the yield of the finished substrate 130 is improved.
Fig. 4 is a flowchart of a method of a cutting method for cutting a substrate, wherein the flowchart shown in fig. 4 is one of the methods of forming a lead-off tilt angle in the flowchart of fig. 3, and specifically, the cutting machine includes a driving device for driving the second cutting machine to tilt; the driving device comprises a Z-axis screw rod and a power module for driving the Z-axis screw rod to move, and the Z-axis screw rod is arranged on the lower side of the second cutting machine platform;
the step of S31 includes:
s311, after cutting, the power module drives the Z-axis screw rod to move according to the angle parameters;
s312: the Z-axis screw rod drives the second cutting machine platform to move, so that the second cutting machine platform and the first cutting machine platform form a leading-off inclination angle.
The Z-axis screw rod is in contact with the second cutting machine table to form a contact point;
the distance between the contact point and the end of the second cutting machine 120 close to the first cutting machine 110 is d1, and the distance between the contact point and the end of the second cutting machine 120 far away from the first cutting machine 110 is d 2; the d 1: d2 is 1: 3. The Z-axis lead screw 141 is driven by the power module 142 to move upward or downward from the lower portion of the second cutting machine 120, so that according to a preset angle parameter, one end of the second cutting machine 120 close to the first cutting machine 110 can be driven to be lifted, so that a required leading-off angle difference is formed between the second cutting machine 120 and the first cutting machine 110, and subsequent leading-off operation is facilitated; and since d 1: d2 is 1:3, which can lift the second cutting machine 120 near the first cutting machine 110, and leave enough space for the tool post and the residue removing mechanism and residue material.
In addition, because these factors of different product characteristics (glass size, thickness, material, glass terminal width, even different cutter types for cutting) all influence the degree of splitting, therefore, power module 142 drive can set up different leading-off inclination angles according to the big base plate of waiting to cut of different sizes, simultaneously, to a big base plate 130, if the leading-off inclination angle effect of once adjusting is not too good, can adjust the leading-off inclination angle repeatedly, to the leading-off angle that accords with various conditions.
FIG. 5 is a method flow diagram of a cutting method for cutting a substrate; specifically, as shown in fig. 5, the cutting machine includes a gripping device;
the step of carrying the finished base plate obtained by cutting to a specified position and resetting the second cutting machine table comprises the following steps:
s51: conveying the finished base plate obtained by cutting to a designated position through the grabbing device, and resetting the second cutting machine to an initial state by the cutting machine;
wherein the leading-away inclination angle is matched with the grabbing angle of the grabbing device. The grabbing device 160 may include a robot arm, etc., and the driving device drives the second cutting machine 120 to form a preset leading-off inclination angle; after the leading-off, the robot arm takes the wafer and is influenced by the horizontal degree of the glass substrate, so the wafer outlet angle meets the horizontal requirement of taking the wafer by the arm, the leading-off inclination angle is set to be matched with the grabbing angle of the grabbing device, the problem of insufficient wafer cracking can be solved, meanwhile, the direct adjustment of the grabbing angle is avoided, the extra cost of the grabbing device is greatly saved, the problem that the grabbing angle needs to be adjusted for many times when the large substrates 130 with different sizes are grabbed or the finished substrates 130 are directly grabbed is solved, the grabbing angle of the grabbing device 160 does not need to be adjusted when the grabbing device 160 grabs the large substrates with different sizes, and the production efficiency is improved; then, the cutting machine 100 resets the second cutting machine to the initial state to facilitate the subsequent cutting operation.
Fig. 6 is a flowchart of a cutting step in a cutting method according to an embodiment of the present application, and referring to fig. 6 in combination with fig. 2 and 3, in order to better improve the problem of insufficient cutting penetration, the present application further discloses that the step of S2 may include:

s22, driving a second cutting machine according to the first angle parameter to form a cutting inclination angle between the second cutting machine and the first cutting machine;
and S23, cutting the large substrate to be cut to obtain a finished substrate falling on a second cutting machine.
The angle parameters comprise a first angle parameter, specifically, the height of one end, close to the first cutting machine, of the second cutting machine is adjusted, for example, the length of the second cutting machine is 300000um, the first angle parameter is an angle for increasing the cutting inclination angle formed by one end, close to the first cutting machine, of the second cutting machine before cutting, and the specific lifting height range is 1um to 500 um; the cutting machine is characterized in that a preset cutting inclination angle is set before cutting, so that the part of the large substrate 130 to be cut, which is positioned above the second cutting machine table 120, can slightly break away from the surface of the machine table due to the cutting inclination angle, and a certain downward self-gravity exists in the part of the large substrate to be cut, which is positioned above the second cutting machine table 120, so that the cutting wheel and the cutting wheel are labor-saving during cutting, the cutting penetration is thorough, the adhesion and other problems are reduced, a good splitting basis is provided for subsequent leading-off operation, partial risks are avoided in advance, and the production efficiency is improved.
